Application filed July 29, 1908. Serial No. 445,959.

To all whom, it may concern:

Be it known that I, BENJAMIN W. T'o'cnnn, a citizen of the United States, and aresident of South Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Flachines for Folding Collars, &c., of which the following is a full, clear, and exact description.

This invention relates more particularly to an automatic rotary machine for infolding the blanks of collars and cuffs.

The primary object of the invention is to provide a machine which is entirely automatic in its operation and in which a rotary drum is provided which carries the blank and during the operation of the machine, the said blank will be automatically infolded and properly creased and pressed and then automatically deposited upon a receiv ing device ready for removal without any handling whatever, except to place the blanks upon the receiving means provided therefor, thus materially lessening the time required for folding articles of the class described by the methods ordinarily employed and at the same time producing the best results without requiring the skill and accuracy of the attendant, as it is required by the usual method.

Other objects of the invention are to provide a simple and effective machine, which will be under the absolute control of the attendant so that it may be operated intermittently or continuously; to provide rotary means adapted to hold a plurality of blanks and simultaneously act upon the same to fold and crease the blanks; to provide simple and efiicient means for heating and ironing blanks both while the templet is still within the folded blank and after the templet has been contracted and removed; to provide simple and efficient means for infclding the blank and confining the same in its folded position during the movement of the parts; and to provide simple and etlicient mechanism for operating and timing the several parts of the invention.

A further object of the invention is to provide means whereby independent devices for heating and pressing the folded blank may be employed; to provide means which will engage and hold the blanks while being pressed, and to provide means to receive the folded blanks properly stacked ready for removal.

In the drawings, Figure 1 is a side elevation of one form of machine embodying my nvention. Fig. 1 is a vertical section showng a part of the mechanism for moving the infolders vertically. Fig. 2 is a front elevation. Fig. 3 is a vertical section, partly in elevation, taken on the line IIIIII of Fig. 2. Fig. 1 is aplan view, partly in section, of the means for operating the infolders.

Fig. 43 is a detail view of one of the fingers and guides of the grid forming a hopper or stacker for the blanks after the same has been folded and on which the blanks are deposited. Figs. 44 to 47 are views of a form of clutch that may be used in connection with the machine to adapt the same to be stopped intermittently. Figs. 48 and 49 are plan and side elevations respectively of the mechanism for intermittently moving the templets; and Figs. 50 to 57 are partly diagrammatic views showing the different steps during the folding of one of the blanks.

lVhile 1 have shown a machine in which a plurality of templets are employed and which form a part of a drum and are adapted to move about an axis, it will be understood that a single or a plurality of templets may be employed and moved other than in a circular direction; that some of the parts may be used in connection with other machines for folding collars and the like; and that various changes in the arrangement and construction of the parts may be made without departing from the character of the invention.

The frame 10 of the machine may comprise two side members 11 and 12 which are suitably braced so as to properly support the several features of the invention, and arranged on the frame between the sides thereof is a shaft 13 from which projectthe arms 14 on the outer ends of which is arranged a receiver or device 15 as shown in Figs. 1, 2, 3, and 40 to 42. The blanks, comprising one or more layers as usual, are placed upon the receiver table 16 between the guides 17 so as to be positioned and supported thereon, and secured to the receiver table 16 are plurality of sleeves 18, which are slidably held in the bosses 19 carried by the arms 14. A rod 20 is secured to each boss and around the rod is a spring 21 which is interposed between the sleeve 18 and the boss 19 so as to yieldingly hold the receiver or device to the arms 14, and on the end of the rod 20 is an enlarged part or collar 22 in which is an opening 23, so that when the arms 14 are forced over from the position shown in Figs. 1 and 40 to that shown in Fig. 41 the guides 17 will engage a part of a platen or table 24 and will hold the receiver 16 stationary and permit the rods 20 to force the blank outward, between the guides 17 and deliver the same on to one of the templets 25 owing to the continued inward movement of the arms 14 as will be presently described.

The arms 14 and the table 16 may be moved in any suitable way. As shown a segment 26, Figs. 39 and 40, is secured to the shaft 13 and in mesh with this segment is another segment 27 which is connected to operate with an arm 28. This arm 28 is connected to a rod 29 at one end and the opposite end of said rod 29 is connected to a lever 30 which is operated by means of a cam 31 secured to the drive shaft 32, so that as the drive shaft is operated the lever 30 through the rod 29 will move the table 16 from the position shown in Figs. 1 and 40 to the position shown in Fig. 41 to deliver the blanks on to one of the templets 25 so as to force the blank over the needles 33 carried by each templet, the said needles being adapted to enter the openings 23 and serve to hold the blanks in position on to the templets.

Instead of a single templet, as in the ordinary form of machine, I employ a plurality of templets and move the same in any suitable way and form each templet so that the plates or members thereof may be contracted or expanded in any desired manner. As shown SlX templets are provided, though this number may vary, and said templets are formed as a part of a rotary drum or turret 3% which is held to rotate with the shaft Each templet may be similarly made and operated and each may comprise a support 36 which has a guiding bed, plate or member 37 of the usual or any preferred construction, and which is adapted to have suitable templet plates movable thereon which define the shape of the article to be folded. As shown, Figs. 19 to 29, a plate 38 of thin metal, from which project the needles 33, is secured to the plate or member 37 of the sup port 36, and arranged so as to move relatively thereto are a plurality of plates 39, a0, ell and i2 forming a part of the templet 25. These latter plates are also of thin material, and are each secured to a slide 43 which may comprise two members and and which are adjustable relatively to each other by means of: the slots 46 and screws or bolts l! so that the movable members of? the teinplet or former may be lengthened or shortened accordin to the length ol the collar or other article to be made, the shape of the plates being raried according to the nature of the article to be folded. The member d-l of the templet plate is secured to a diagonally movable plate, block or slide 48; the member t l of the plate 40 to a block or slide 49; the member 44: of. the plate ll to a slide or bloclr 50, and the member i lof the plate 42 or" the templet to a slide or block 51. The slides or blocks of the several templet plates, intersect each other in pairs, and are movable one above the other, and blocks 48 and 49 are connected by the transverse or cross-bar 52 to work .in unison, while the blocks 50 and 51 are connected by the transverse bar 53 to cause said blocks to move in unison and either inwardly or outwardly to contract or expand the templet plates as is usual in machines of this character. The transverse bars ti grooves in the slides or blocks to perniit them to move relatively to each other, and the transverse bar 5o is connected by a link to one end of a lever 55, and the other end of said lever is connected by a link 56 to the transverse bar 52, and said lever is located under the plate or member 37, and when said lever is moved in one direction it will expand the templet plates and in the other direction will contract or collapse the same, the templets and adjusting leans described being of the usual or of any preferred construction.

The table or platen 24;, one for each templet, cooperates therewith and forms a part of the drum 234i and each platen comprises two members 57 and 58 which are adjustable to or from each other, and each member may comprise two plates and an intermediate plate whereby the latter may be removed and a plate of diflerent size substituted therefor, so that the plates or members 59 may be adjusted to or from each other, the said adjustment of the plates 59 being secured by means of thumb nut-s (50 the stems of which pass through slots 60 in the members 57 and 58, thus permitting the parts of the platen to be adjusted transversely and lengthwise to adapt the same to different sizes of collar blanks and the like and to vary the size of the opening formed between the members of the platen according to l'llG size of the templet used, and also that the inner edges of the members or plates ot the platen may engage those of the collar which has been infolded as will be hereafter explained.

The platen is supported by means of the arms 61, Figs. 15 to 18, and these arms are held to vertically movable rods 62 around which are the springs 63, and these springs (33 are interposed between the arms (51 and the bosses (B t of the support 36 which is rigidly held so as to form a part of the drum 34:. The rods 62 are provided with an enlarged lower end and are arranged in pairs, and one pair is operated by the ends 67 of levers (58 which are secured to the shaft (39, and the other pair are operated by the ends 70 of levers 71 which are secured to the shaft 72 arranged parallel to the shaft 6.). T he ends of the rods are enlar d for proper engagement with the ends o'l said levers 68 and 71 and these levers at their inner ends are provided with teeth forming segments which intermesh. To each shaft 72 is so cured an arm 7 3 and on this arm is a roller 74: which is adapted to travel around the periphery of a cam 75. The cam 75 has a movement on the drum shaft but is not fixed to rotate therewith, and said cam has its surface so arranged that as the arms rotate around the same the said cam during such movement and by reason of a relative movement of its own, as will be presently explained, will cause the arms to shift their positions and through said arms and the levers G8 and 71 lower the platen, the normal action of the springs 63 being to force the platen outwardly. The independent movement of the cam 7 5, Figs. 30 and 31, is secured through an arm or lever 76 which is held at 7 7 to the cam, and has its other end slotted so as to be guided by the drive shaft 32, and on the shaft is a cam which has its cam groove 79 so formed that it will cause a reciprocatory nuiwement to be imparted to the arm 76, the said arm 7 6 being provided with a roller 80 or other engaging means adapted to travel in the groove of the cam 78. The cam 75 is provided with a raised part 81 to cause an inward movement of each platen relatively to its templet as the arms for moving the rods 62 travel around the cam 7 5, and said cam is provided with a cut-away part 82 or jog whereby each platen may be forced outwardly by the springs 63 when the cam 75 is given an independent movement on the drum shaft 35 through the arm or lever 76. By this means the cam 7 5 may be so formed that it will permit the arms 73 to move inward or outward while the drum remains stationary in order that the blank may be properly acted on and the platen made to cooperate properly with the templets, the infolders, and other parts, as will be more fully hereinafter explained.

The cam 75 is located on the shaft 35 at one side of the machine and on the other side of the machine is a cam 83 which is adapted to operate the templet plates to contract or expand the same. This cam 83 is held on the shaft 35 so as to be shifted relatively thereon in the same manner as the cam 7 5 and secured to the cam 83 is an arm or lever 81 which carries a roller, as at 85, which is adapted to travel in the cam groove 86 of a cam 87, the latter being secured to the shaft 32 so that as said cam 87 is rotated the cam 83 will be given an independent movement around the shaft 35. A plurality of arms 88 carrying rollers 39 and held to the shafts 90, one for each templet, are arranged to move around the periphery of the cam 83, and said arms are normally forced inward by the springs 91, Figs. 2 and 20, against the action of cam 83. The shafts 90 are each provided on its inner end with a bevel gear 92, and this gear is in mesh with a similar bevel gear 93 held to the lever or arm so that said lever may be operated and through the links 51 and 56 contract or expand the plates forming the templet.

Each templet is provided with one or more of the needles 33 which are adapted to enter the blanks when the same are carried forward and inward by the receiving device 15, and by reason of the action of the rods 20 the blanks will be forced from the table 16 and will remain upon the templet. As the templets revolve through the rotary movement of the drum, which latter is intermittently operated corresponding to the distance between any two templets, and as soon as a templet has received a blank from the device 15, the drum will be given a movement to place the blank under the infolding mechanism 91. This mechanism 91 may be variously constructed. As shown a single infolder means is used for the several templets and said mechanism is arranged in the upper part of the machine frame and is supported on a bracket 95 of said frame and is movable to and from each templet as the latter are successively placed in position with the blank to be "clded under the same. The infolder mechanism comprises two main members or infolder-s 96 and 97, Figs. 1 to 8 and 13 and 14, and these infolder plates or members may comprise a plurality of parts as 98, 99 and 100. The part 99 is adapted to be made of any suitable size to adapt the infolder plates or members for different sizes of collars and cuffs as is usual, and said members are cut away at their inner edges and opposed so as to engage the blank to infold the inner edge thereof under the templet plates or members, the parts of one plate or member of the infolder being adjustably held to a block or head 101 and the parts of the other member to a head or block 102. The head 101 of the infolder mechanism is supported by the rotary shafts or studs 103 and 101 at one end and by the studs or shafts 105 and 106 at the other end, while the head or block 102 is supported and carried by the shafts 107 and 108 at one end and at the other end by the studs or shafts 109 and 110. Each stud or shaft is eccentrically held to a part or disk 111 which is located and movably held in a boss 112 formed as a part of the infolder frame head 113. As the parts 111 are rotated the shafts 103 to 110 will be given an eccentric move ment and during such movementwill force the heads 101 and 102 toward or from each other so as to cause the infolder plates to move inwardly or outwardly according to the direction of movement of said parts 111. The parts 111, and the shafts connected therewith for operating the infolder plates, are arranged in pairs, each pair being oper ated by gears 11 1 and 115 which are secured to or formed integral with the parts or eX- tensions 111, and said gears 11st and 115 are operated by an intermediate gear 116. The intermediate gears 116 are each operated through a bevel gear 117 by a shaft 117 having a key and slot connection with the bevel gear 117 to permit vertical movement of said shaft, and said bevel gears are each in mesh with a second bevel gear 118 located on each end of transverselyextending shafts 119 and 120 at the front and at the rear f the machine. The shaft 120 through the gears 117 and 11S operates the rear infolding plate while the shaft 119 operates the forward infolder plate and moves said infolder plates inwardly or outwardly according to the direction of movement of said shafts.

The infolder operating shafts 119 and 120 may be rotated in unison so that the infolder plates will move together or they may be moved one in advance of the other as preferred. To effect this 1 secure to the shaft 119, Figs. 4 to 12, a toot-lied wheel or disk 121 and to the shaft 120 a toothed wheel or disk 122. The wheel 122 is adapted to mesh with a segmental gear 125 and the wheel. 121 with the segmental gear 120. The gears 126 and 125 are relatively movable with respect to each other by means of the screws 127 and 128 which are adapted to engage teeth on the periphery of a drum 129.

The screw 127 when rotated will move the gear 125, while the screw 128 will move the gear 126 around the toothed drum 129, and in this way will cause the segmental gears to simultaneously engage the teeth of the wheels and 121 to rotate the same in unison as shown in Fig. 12, but when. said gears 125 and 126 are moved relatively with respect to each other the said gears will operate the wheels one in advance of the other as shown in Fig. 10, so that the infolder plates may be made to move in unison or one in advance of the other as desired. To the shaft 119 is held a locking element or foot 130, and to the shaft 120 is held a looking element or foot 131. Each element or foot is provided with curved or recessed portions corresponding to the periphery of a part of the segmental gears 125 and 126, and are adapted, after the shafts 119 and 120 have been rotated, to hold the same and properly position the infolder plates, the segmental gears being cut away to permit proper movement of the locking elements. An arm 132 is secured to the drum member 129 of the adjusting means and this arm is connected by a link 133, O, to one end of a lever 13 1. The arm 135 of the lever 134: is provided with a roll or other engaging means which is movable in the groove of a cam 136 secured to the 'ive shaft 32, so that as said shaft rotates the lever 13 1 through the link and arm 132 will open and close the infolder plates at the proper time and in unison or in advance of each other as preferred.

The infolder plates have a vertical movei'nenttoward and from the templet plates, and from the infolder frame head 113 project one or more sleeves 137. These sleeves 137 are slidingly held in the bracket 95 in which the shafts 119 and 120 are journaled, and on the upper end of said sleeves are arranged collars 138 which are engaged by the forked ends of arms 139. The arms 139 are secured to a shaft 1&0, Figs. 1 and 6, journalcd in the upper part of the machine frame, and to said shaft is held an arm 141 which is operated by a lever 141-2 by means of a cam 1 1-3 located on the shaft 32, so that as said shaft is operated the infolder frame head 113, together with the infolding plates and means supported thereby, will. be moved toward or from the templets as they are successively presented under the same, the shafts 117 of the intermediate gears 116 being provided with a suitable connection with the gears 117 to permit this vertical movement.

A matrix. or folding element 14% is movable with the infolder frame head 113, and this element or member is independently movable of the infielder plates. The element 1 141 is provided with pendent flanges 14-5 corresponding in form and structure to the templet plates and may comprise a plurality of members as 1.416 and 13-17, Fig. 14:, which are adjustably held together to adapt the same for different sizes of collars or the like, and said element is held to the rods 1.48 which project upwardly through the sleeves 137 and at the upper end thereof are each provided with a stem 1 19 around each of which is arranged a spring 150. The spring 150, Fig. 6, is confined between the ends of each red 1 18 and a collar or nut 151 and serves to yieldingly hold the element '11 to the sleeves 137 and the infolder frame head 113. The purpose of the element 1 1. 1 is to fold the blanks about the edges of the templet plates when the latter are in an expanded position and as the infolders are moved downwardly, and to hold the blank while the infolders are forcing the lower edge of the blank under the templet plates. In this position the platen moves upward before the withdrawal of the infolders so as to prevent the withdrawal of the inturned edges of the blank and as soon as the in folders are withdrawn from under the templet the said platen or table is moved far enough to grasp the infolded edge of the blank between the templet and platen and hold the same as the infolder head and the element 14A and infolder plates are raised. leaving the blank folded. about the templet.
